.To @ZZ whom it may concern.

Be it'known that I, FREDERICK G. WISE- LOGEL, a citizen of theUnited States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Extractors and Evaporators for Garbage,&c.', of-which the following isa specification'.

The object ofmy'said invention is to produce an apparatus for extracting grease, &c.,

from garbage, and for evaporating and drawing of' the extracting agent to a condensing apparatuswhere it may be prepared to be used again. Y

It consists mainly in the construction' of f the car which carries the garbage and in which it is treated.- 4 i p It also consists in some improvements in the construction and arrangement of the retort.

Anapparatus embodying my said invention will be first fully described, and the novel features thereof then pointed out in the claims. y

Referring to the accompanying drawings, which are made apart hereof, and on which similar letters of reference indicate similar parts, Figure lis a side elevation of the tank forming the outer casing of` my improved extractor and evaporator, with the side broken open to show the interior; Fig. 2, an end elevation with the door swung open, and show- 'soV ing a fragment of the door; Fig. 3,'a transverse sectional view of the structure as seen from the dotted line 3 3 in Fig. l; Fig. 4C, a

View, partly in end elevation, and partly inA section, of the car separately, on an` enlarged. scale, and Fig. 5 'a detail sectional view of' the front corner ofthe car and immediately adjacent parts, including a fragment of the door, the pipe coils being omitted.

In said drawings the portions marked A represent the exterior casing of the retort of said apparatus, B B B2 C and D the coils of pipe therein, 4and E the car containing lthe matter to be treated. n Y

The retort casing A is in form a large cylinder, having various ingress and egress pipes forthe steam, vapors,-grease andv other products, and one end has a large door Awhich covers the entire end, and which is adapted to be swung back and forth yon a hinge-.rod h plained. Inside it is provided with a track .a for the car,1and near the bottom it has a roof-like shield or plateA2 beneath which thev extracting 'agent may flow, and where, by being subjected to heat, it may be evaporated and driven up, either to be condensed and drop on to the mass in the car, and its use thus continued in the same operation, orv driven away to a receptacle and collected for subsequent use, according to ,the ,circumstances of the case, and as will be presently further explained; Said shield v or plate A2 prevents the extracting agent (usually a hydrocarbon, such as benzine) from rrising in fumes through the car and the matter therein being treated, but instead drives said fumes oh' to the sides of the'apparatus, Where they which is being treated. The coil of ,pipe C belowthe plate A2 is also a steam pipe,and is for the purpose of evaporating-the hydrocar- -bon from the liquid matter which collects at s the bottom of the tank, when that operation is desired, andmay also be employed to assist in heating the apparatus generally. The coil of pipe D at the upper side of the apparatus, above the car, is intended for a cold water coil, by means of which, upon occasion, the

densed. The operation of the various coils will be Vexplained hereinafter more in detail.

The car E is composed of several cells (four are shown)separated by open spaces,'which hydrocarbon vapors or fumes may be con- IOO `spaces are covered by roof-like covers r,

said cells-being held apart by stay-bolts surrounded by collars c, as shown most plainly in Fig. 4. All the iron plates from which this car is formed contain a large number of perforations, so that air, steam, liquids and va'- pors may freely pass through. The bottom of the cells are made up of removable perforated pipes E', carried preferably byremovable plates E2, which in turn are supported in housings E3 secured to the ends ot' the car, by pins e2, so that by removing said pins said pipes and their supporting plates can be easily removed and the contents of the car thus discharged. If desired, steam or other pipes might be connected to the ends of these pipes E', and liquids or vapors driven through them and through their perforatious into the mass of matter being treated, but this will ordinarily not be necessary. The car as a whole is carried by an axle E4on wheels E5, and on said axle are collars e, by which the car is held from movement thereon. The axle is preferably made stationary, While the wheels revolve.

The operation of my said invention is generally substantially as follows: The material to be treated is put into the cells of the car, and when these are filled the car is run into the retort or extractor composed of the casing or cylinderAand its various coils and attachments. The door A is closed and bolted tight. If the material is to be treated chemically, benzine, or such other solvent as is used, is first introduced into the retort until it covers the car and contents. Steam is first turned on to the coil C at the bottom of the retort, just enough to heat but not to vaporize the solvent. After standi'ng awhile in this condition, the entire solution is drawn olf through the pipes at the bottom of the retort (shown most plainly-in Fig. 1), preferably into suitable evaporators, where the solvent is evaporated out of the grease, and, after passing through suitable condensers, is allowed to ilow back into a storage tank, whence it may be taken and used over again. If by this rst operation the extracting is not completed to the extent desired, the solvent is carried back to the extractor and thrown on top of the material in the car and allowed to pass through it to the bottom. At the same time water is turned on the condenser coil D at the top of the retort, and steam into the evaporator coilat the bottom. As the solvent passes through the mass it takes the fatty matter with it, and falling on the deilecting plate A2 flows down the same to the bottom of the retort, where it strikes the hot pipe of the coil C, when the hydrocarbon or solvent is again vaporized the vapors or fumes following the sides of the retort and car to the top, where, striking the cold coil D, they condense again, and, falling on the mass in the car, the solvent passes down through as before; and this operation is kept up until all the fatty matter is dissolved and taken ont of the material. This done, the water is shut od the condenser coil D, the valves of the escape'pi pes p ou top of the retort are opened, and the vapors or fumes will pass through these pipes, which are connected to condensers, where the solvent is condensed and allowed to iiow back into the storage tank as before. Steam is then turned on all the pipes, except the condenser coil D, and all benzine, or other solvent, and moisture, is driven off by the heat thus applied. Grease, the., being freed of the solvent, is drawn off from the bottom of the tank A by means of the pipes at that point into suitable receptacles. The heating is then continued, and when all the moisture is driven otl through the large escape pipe P at the top of the retort, the steam is shut off; the retort opened; the car taken out; another putin, and the operation repeated. The finished load is wheeled to such place as is designated for the dried stuff, the pipes E at the bottom of the car withdrawn, and the material allowed to fall out by its own gravity.

If the material to be treated is of such na ture as not to warrant the expense of hydrocarbon treatment, hot water is pumped into the retort instead, and steam turned on all the coils except the condenser coil on top, and the whole mass brought toa boil, and, under a moderate pressure, is allowed to stand for a suitable length of time. The gas produced by the operation being atall times allowed to pass through the main pipe I (which is connected to a suitable condenser and retort) allv microbe and disease germs that may be present in the material under treatment are eectually destroyed. Such grease as may be extracted and is floating on the water, is drawn olf, and all the water is drawn off or entirely evaporated, the valve in the main pipe P is opened full, and all the vapors and gases pass through it and through the condensers and retorts to beneath the boilers or elsewhere as before explained.

If the material to be treated is such as would float on the liquid in the retort during the irst part of the operation above described, covers of similar material as the car sides may, of course, be provided, to hold it in the cells, as will be readily understood.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, itt-an extractor and evaporator for garbage, dac., of a retort composed of a large cylinder or tank having a IOO IIO

door at one end, the heating coils within said retort, the heating and evaporating coil C,

the condenserfcoil D, suitable ingress and V egress pipes, a plate or shield A2 between the coils "B and C, and asuitable car for carrying the matter 'to be treated, substantially as shown and for the purposes set forth.

, 2. The combination, in an extractor and evaporator, with the retort, of a car composed of cells built up of perforated plates, with open spaces between the cells, whereby the evaporator, of a car formed in cells composed of perforatedplates, the cells being' separated by open spaces, perforated removable pipes forming the bottoms of said cells, and hanger' plates carrying said pipes.

In Witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this v21st vday of September, 1894.
